Light Years to Parsecs Converter
Definition
A light year (ly) is the distance that light travels in a vacuum in one Julian year (365.25 days), approximately 9.46 trillion kilometers or 5.88 trillion miles. A parsec (pc) is a unit of length used in astronomy, equal to about 3.26 light years, 30.9 trillion kilometers, or 19.2 trillion miles. It is defined as the distance at which one astronomical unit subtends an angle of one arcsecond.
History
The light year was first proposed by friedrich bessel in 1838 for measuring astronomical distances, though the term itself was popularized later. The parsec (parallax second) was introduced by British astronomer Herbert hall turner in 1913 as a more directly measurable astronomical unit. It derives from the method of stellar parallax, where the distance to nearby stars is determined by measuring their apparent shift in position when viewed from different points in Earth's orbit. While light years are more commonly used in popular science communication, parsecs are the standard unit for professional astronomy and astrophysics. Both units are essential for expressing the vast distances between stars and galaxies.
